DESCRIPTION
       dspam_maintenance is used to remove old signatures/tokens and unimportant tokens from the  DSPAM  storage
       backend and purge old log entries in user and system logs.

       This  script  can  be  called  from  the  command line or run from within cron. Either add a line in your
       crontab or add this script in your cron.{hourly,daily,weekly,monthly}.  Running this  script  every  hour
       might not be the best idea but it's your decision if you want to do so.


OPTIONS
       --profile=PROFILE

                     Specify a storage profile from dspam.conf. The storage profile selected will be used
              for all database connectivity.

              NOTE: See dspam.conf for more information.

       --logdays=no_of_days

                     All log entries older than

                     All signatures older than
              no_of_daysdays will be removed.

              NOTE: Default value is set by the PurgeSignatures option in dspam.conf, if this option is not set,
              the default value is 14 days. This option is only used for the Hash driver.

       --neutral=no_of_days

                     Deletes all tokens from the target users database whose probability is
              between 0.35 and 0.65 (fairly neutral, useless data).

              NOTE: Default value is set by the PurgeNeutral option in dspam.conf, if this option  is  not  set,
              the default value is 90 days.

              default value is 90 days.

       --hapaxes=no_of_days

                     Remove tokens with a total hit count below 5 (which will be assigned a hapaxial
              value by DSPAM).

              NOTE: Default value is set by the PurgeHapaxes option in dspam.conf, if this option  is  not  set,
              the default value is 30 days.

                     Remove tokens with a single SPAM hit.

              NOTE: Default value is set by the PurgeHits1S option in dspam.conf, if this option is not set, the
              default value is 15 days.

       --hits1i=no_of_days

                     Remove tokens with a single INNOCENT hit.

              NOTE: Default value is set by the PurgeHits1I option in dspam.conf, if this option is not set, the
              default value is 15 days.

       --without-sql-purge

       --purgescriptdir=directory

              Space separated list of directories where to search for SQL files used for the SQL based purging.

       --with-all-drivers
